ok, i am stuck again.

from the docs, the byte stream is supposed to look like this:

'S' 'T' 'X'   [length indicator] [message type] [message] 'E' 'N' 'X'

the length indicator it says is a four byte integer number of a value N
 ( N would be how long the message body is )

the message type comes from a table in the docs. In my case, the
message type is 200. This is also supposed to be sent as  a 4 byte
value.

so..... how do i make 200 occupy 4 bytes ?
